now stay your eyes closed and your head toward anything else than your guinea pig arm under test. When it's clear for you tu tell right if one or two tips are pressured on your skin and where they are by the pressure sensors grid feeling alone,not your eyes,brain compensate sense
To come back on our arm piercing pratice. Get back your friend, two pens or alike. Close eyes and look at something in oposite direction to be sure to not look even without being consious that you open yout eye a little because tactile sensations are for most people linkd vision

-
now I'l get through the right thing and stop getting lost in tought ask your assistant to pin your skin on the forearm with one or two, sharp tips , and tell by tactile feeling only the number of points are pressing the skin. If you have more than 2cm betweek the two pens,
-
You should dobn't have hard time to guess correctly. The test of using only skin sensors not assisted by vision is not common and at beginning the right count of points with enough space between, can seems disturbind without cheating by correcting the touch sensation by visual
-
informations, that are probably part of unconcius data processing, of vision, asserting by object reckognizing the number and location of touch feeling; the image you see can even take precedence over tactile sensations, vision of something touching your skin will make feeling
-
& being sure that sensing something touching your skin, or piercing in it, or digging it, or walking over the surface is in fact a phantom artifact and vision confirm an absence of something in contact with skin,or anything (and you are not in a panic mode) Mute the false feel
-
ok you all had understand the point that vision can create or mute the sensory information prvided by skin: pressure , light pet, air flow against skin, and all kindof tactile feelings that are in fact combination of activation at some intensity of "pressure detection network "
-
and often solicitated too the betwork of skin thermosensors taht give a progressive signal of the temperature gradiant between the body controled fixed for humain metabolism about 37.5 and is maintened at this temp when nothing wreck the whole thing, often by getting up
-
in reaction to the presenve of some ifection but I'm not sure if this is the brain that react by using defense mechanism,maybe hope that getting a little of problem is,sometime dangerously close to crtical point
-
when reaching the point of out of bound themperature with all you organism failing becuse proteins badly fold & enzymes are not working anymore besause they need a small range of surround °C, to be effective catalyst and cut molecule in ther active site,or bound some together
-
or if the dysregulation of themocontrol is due to toxins released by pathogenes infecting the body. toxins targeting the themoregulation in brain and leading to fever. Or maybe it's a very dumb reflex when infection is detected to get rid of thing that won(t like to have 39,5°C
-
very dumb because that's not often effective I think, and the whole bodyu metabolism is getting really not well working, and can die of this mneuver. and at the same time, sometime caused by toxins released that trigger misregulation of body temperatire.
-
With the combined sensation of pressure detection in the skin, and temperature detection when the thing touching the skin is not close to the bofy reference temperature. Ambiant air hot is feelt on the skin by a strange feeling like a pain without pain (excepted vry hot& cold)
-
when the temperatures differencial is not too hight, we perceive cold and hot like 2 very distint perception, but it seems that the sensory os maybe encoded in the DNA, at really low level, we know that we should stay in a neutral range where temperature outside is not enought
-
not enought to become an input from themoception, and I think we all know intuitively that the feeling of hot and cold, are both leading to not a temperature reading with an intensity increasing with the difference between out env on the skin, and in ref tht kept @ hardcoded val
-
but reasing in hot temperature, and cooler, and reaching the danger threshold where the thing we touch can be dangerous and burn the skin, or is already burning flesh since precious nanosecond delay betwen dmgs & percepton o pain&+hot obj. at this difference°C feeling become pain
-
the last sensor in network ovrt the skin, and playing a role in the global feeling that we call tactile sensation on skin. I'll be quick here, these are nocicepteurs sensors, deep in the skin, activated by somme triggers that are felt as painful.
-
Being bite gently by playing dog, and you will feel pain only if the max is pressing enought of teeth to risk if pressure raise again , to pierce throughskin, and the painfulness of the biting will increase an become long lasting activated if the skin is damaged near the sensor
-
return to the experiment I try to explain since few hours and keed loosing myself on telling things that are not useless but not the subjecy at all and I doubt that anyone read the amount of text I've put because of ... not really know, I just commented my opinion on few subj
-
One you have no difficulty telling withou your eyes in the equation, how many points pressured on forearm and their estimated (roughtly) distance from each other.Then the more interesting thing, you'll tel your friend to now decrease progressivel space netween the two pens
-
I'll spoil you but if you are not some strange shit that turn more pressure sensor in your skin,or less and 2cm between points were already for yu not segregated without a look at the arm. you should with closedeye & nocheating , reach a point where suddently you don't feel 2 pen
-
For a total fooling of the sensorial input it's really more effective if you push them in the skun with less space than the than the sensors resolution on the arm, if you puy one tip then the other, you will trigher further press sensor by stretching skin a little thrn 2 landing
-
It"s about 1cm for most people, than toutching is not precise enough excepted he hand and the tip of fingers, that have a resolution so good that blind man are teached how to read by describing y tactile input only from a finger sliding on thtext made of little dots bumping
-
they can witn gōd spēd when usd 2 ths method reading withou sēing,count number dots tht was under finger,& also the position of each point in the two collumns. Finger tips are probably tje only part of the skin with a sensor so fine that 1mm space enough to feel separated bumps
